[Bug 566203] [NEW] Acer AspireOne 751h: can't lower/increase brightness

I have an Acer AspireOne 751h laptop with an Intel GMA500 Poulsbo video
card.  It is running Ubuntu Karmic and has been configured with the psb
driver, so X server is working fine. However, the brightness keys don't
work (Fn+left/right arrow).  I am able to lower/increase with
xbacklight, so I know screen brightness can indeed be lowered/increased
on the laptop.  So the problem lies in the fact that the key
combinations (Fn+left/right arrow) are not recognized.

Interestingly, if Bluetooth is turned off using the Bluetooth switch or
using Fn+F3, it not only disables Bluetooth but the brightness increase
OSD dialog pops up.

This is the same problem described in
